Happy baby but cries to drink milk

Shashi

Hey mamas! I have a rather normal baby who doesn’t cry at all is reaching all of his milestones and is smiling all the time except when he has to drink milk and is falling down the charts. The pediatrician prescribed Zantac as we had a feeling he was suffering from silent reflux. He has been on it for the past 24 hours. Though he’s not crying anymore he barely takes 2 oz. If we give a gap of 4 hours he still drinks 2oz. I know he has capacity because he used to drink 3.5oz in the past. How do I get the intake to be increased and also anybody had positive feedback with Zantac. I’m worried that they might say FTT. How do I get my baby to drink more. Please help

This is my cutie each time I feed him my heart breaks that he’s not getting enough nutrition. He’s getting BM in a bottle I stopped eating everything that would cause him reflux. I have no idea what else I can do at this stage.
